Description Yang Dehua 2003-05-28 02:38:43 UTC

Version:            (using KDE KDE 3.1.2)
Installed from:    Mandrake RPMs
OS:          Linux

open konqueror, turn on 'show hidden files',switch to tree view. Descend into a hidden directory (for me it was .kde/share/config/) without entering it (just clicking the '+' ) then unset 'show hidden files'--The Konqueror crashed.

Comment 2 Maksim Orlovich 2003-05-28 03:03:07 UTC

I should have said this the first time:  
Thanks a lot for your report, your reproduction instructions are excellent, so this 
report will likely help a great deal in figuring this and related issues out.  
I'll re-paste the backtrace now, in case there are other reports with crash but 
w/o this level of the detail; there is an automatic tool here to search for cases 
like that, but it didn't work the last time since I cut off a few of the 
"non-interesting" things it apparently uses to synchronize.
